摘要: AbstractThis work concerns the optimization of neutralization dialysis process applied to water desalination. This is used for salt removal from a NaCl model solution (initially 0.08 M) in three-compartment membrane stack (acid, salt, and alkali compartments) with cation-exchange an anion-exchange one, i.e. Neosepta® CMX AMX, respectively. The desalination has been investigated as function three main parameters, namely initial concentration flow rate acidic alkaline solutions well saline volume. A fractional factorial design, 25−1, employed assess parameters affecting efficiency, specifically study ion-exchange H+ Na+ through that OH− Cl− AMX. linear theoretical based on experimental results carried out account influence different their relative interactions. analysis vari...
